Description of problem:

This one needs a bit of specific numerology to reproduce.
I noticed it in one of my VMs by chance.

Basically:

• Pre-configured PV of 563G (I'm using LSO)
• VM disk PVC of 500G binds to the PV above

Result: the UI shows the disk as 512KiB.

If I move things around (i.e. change some of the sizes, the problem goes away).

Version-Release number of selected component (if applicable):
4.12.2

How reproducible:
Always

Steps to Reproduce:
1. Using LSO, create a 563G partition (I have some of 100 and 200G which do not reproduce)

$ sudo fdisk -l /dev/sda | grep -E 'Device|sda14 '
Device Start End Sectors Size Type
/dev/sda14 2726299648 3907029134 1180729487 563G Linux filesystem

2. Let LSO create the PV for it

NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
local-pv-6079dbae 563Gi RWO Delete Available local-ssd 27m

3. Create a VM disk in such a way that it will bind to the PV above. But request only 500G

NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
fedora-disk-bad-swift Bound local-pv-6079dbae 563Gi RWO local-ssd 30m

4. Navigate to the console, Virtual Machines -> VM -> Disks. See the size it reports.

See the screenshot attached for the exact case above.

Actual results:
512K

Expected results:
563G
